Abstract

A method for creating a distance dependent display that comprises providing an image separating mask having a plurality precision slits arranged in a pattern, generating an interlaced image from a plurality of images according to the pattern, and combining the interlaced image and the image separating mask to allow an observer to view substantially separately each the image from a respective of a plurality of different distances from the image separating mask.

Claims

1. A method for creating a distance dependent display, comprising:

providing an image separating mask having a plurality precision slits arranged in a pattern set so as to create different parallel viewing windows at different viewing distances;

generating an interlaced image that combines strips from a plurality of images according to said pattern; and

combining said interlaced image and said image separating mask to create a distance dependent display that allows an observer to view substantially separately each of said plurality of images from one of a plurality of different viewing positions at a plurality of different distances along a virtual perpendicular to the face of said distance dependent display;

wherein said plurality of images are interlaced so that image strips of each one of said plurality of images are viewed by both eyes of said observer via the same precision slits of said plurality of plurality precision slits of said image separating mask when said observer is in one of said plurality of different viewing positions.

2. The method of claim 1, wherein said pattern is irregular.

3. The method of claim 2, wherein said irregular pattern is selected from a group consisting of:

an asymmetric pattern of opaque and transparent sub-areas, a pattern having opaque segments with variable widths, a pattern having transparent segments with variable widths, and a pattern in which the various segments having variable opacities.

4. The method of claim 1, wherein said plurality of precision slits comprises a member selected from the group consisting of linear slits, curved slits, annular slits, twisted slits, spiraling slits and/or kinked slits.

5. The method of claim 1, wherein said combining comprises attaching said interlaced image to a side of a transparent surface and said image separating mask to an opposing side of said transparent surface.

6. The method of claim 1, wherein said providing comprises arranging said plurality of precision slits according to a binary image.

7. The method of claim 1, wherein each said image having at least one of a different hue and a different color, wherein the hue perceived from each said distance is different.

8. The article of claim 1, wherein said observer views substantially separately each of said plurality of images with both eyes.

9. A distance dependent display, comprising:

an image separating mask having a plurality of precision slits arranged in a pattern set so as to create different parallel viewing windows at different viewing distances; and

an interlaced image that combines strips from a plurality of images, each said image being interlaced to match said pattern;

wherein said interlaced image and said plurality of precision slits are aligned to allow an observer to view substantially separately each said image from one of a plurality of different viewing positions at a plurality of different distances from said image separating mask along a virtual perpendicular to the face of the distance dependent display such that each said image is substantially separately viewed by said observer from another of said plurality of different distances;

wherein said plurality of images are interlaced so image strips of each one of said plurality of images are viewed by both eyes of said observer via the same precision slits of said plurality of plurality precision slits of said image separating mask when said observer is in one of said plurality of different viewing positions.

10. The distance dependent display of claim 9, further comprising a transparent surface, said transparent surface said interlaced image and said image separating mask being attached to opposite sides of said transparent surface.

11. The distance dependent display of claim 10, further comprising an attachment element for attaching the distance dependent display to a window.

12. The distance dependent display of claim 10, wherein said image separating mask comprises a member of a group consisting of:

a parallax barrier, a grating, and an optical barrier.

13. The distance dependent display of claim 10, wherein said image separating mask is an optical barrier, said plurality of precision slits comprising a member of a group consisting of lenticular lenses, diffractive elements, and lenses for integral photography.

14. A method for creating an integral viewing sheet, comprising:

providing an image separating mask having a plurality of precision slits arranged in a predefined pattern set so as to create different parallel viewing windows at different viewing distances that applies an estimated blur;

interlacing strips from a plurality of images to form an interlaced image according to said predefined pattern, at least one of said interlaced image and plurality of images being processed according to said estimated blur; and

creating an integral viewing sheet by fixating said image separating mask in parallel to said interlaced image;

wherein said predefined pattern is set so that in each one of a plurality of different viewing positions at a plurality of different distances from the image separating mask, along a virtual perpendicular to the face of said distance dependent display, an observer views, by both eyes and via the same precision slits of said plurality of plurality precision slits of said image separating mask when said observer is in one of said plurality of different viewing positions, image strips of a different image of said plurality of images such that each said image is substantially separately viewed by said observer from another of said plurality of different distances.

15. The method of claim 14, wherein said predefined pattern is irregular.

16. The method of claim 15, wherein said irregular pattern is selected from a group consisting of:

an asymmetric pattern of opaque and transparent sub-areas, a pattern having opaque segments with variable widths, a pattern having transparent segments with variable widths, and a pattern in which the various segments having variable opacities.

17. The method of claim 14, wherein said image separating mask has a transparent-opaque ratio of at least 1:

1.

18. The method of claim 14, wherein said interlaced image comprises a plurality of strips, at least one of said plurality of precision slits being wider than each said strip.

19. An article for viewing images of an interlaced image, comprising:

an image separating mask having a plurality of precision slits arranged in an irregular pattern set so as to create different parallel viewing windows at different viewing distances; and

an interlaced image from strips of a plurality of images, each said image being interlaced to match said irregular pattern;

wherein said interlaced image and said plurality of precision slits are combined to allow an observer to view substantially separately each said image from a respective of a plurality of a plurality of different viewing positions at a plurality of different distances from said image separating mask along a virtual perpendicular to the face of the article;

wherein said plurality of images are interlaced so that said observer views, by both eyes and via the same precision slits of said plurality of plurality precision slits of said image separating mask, image strips of one of said plurality of images substantially separately from other of said plurality of images at each one of said plurality of different viewing positions such that each said image is substantially separately viewed by said observer from another of said plurality of different distances.

20. The article of claim 19, wherein said irregular pattern is selected from a group consisting of:

an asymmetric pattern of opaque and transparent sub-areas, a pattern having opaque segments with variable widths, a pattern having transparent segments with variable widths, and a pattern in which the various segments having variable opacities.
